The 23-year-old scored twice in the final 10 minutes for the Dragons in their 2-1 comeback victory over Scotland in Cardiff on Friday.
"He's a very dangerous player and scored twice against Scotland and Bale can be a dangerous man in Tuesday night's game," the Croatian Football Federation president told BBC Wales.
"He's a great football player and good for football to have great quality players. I wish him all the best but not on Tuesday night."
Croatia are currently second in Group A with seven points from three matches, while Wales are four points behind them in fourth.
